中文摘要	为探讨新疆绿洲区不同灌溉方式及灌溉量对苜蓿田间土壤水分空间分布及运移的影响,在苜蓿生长第二年设滴灌和漫灌两种灌溉方式,每种灌溉方式设3个灌溉梯度,对土壤含水量进行了测定与分析。结果表明,苜蓿生长季内,随生育进程的推进及灌水次数的增加,土壤水分含量呈波动式递减变化趋势。灌溉后垂直方向上0~40 cm、水平方向上0~30cm土层土壤含水量明显增加,且垂直方向上土壤水分湿润峰明显大于水平方向。苜蓿整个生育期随灌水量及收获茬次的增加,水分利用效率逐渐下降。滴灌和漫灌水分利用效率分别为4.55~5.48 kg/(mm·hm~2)、3.21~3.81 kg/(mm·hm~2),与漫灌相比,滴灌方式总水分利用效率提高了42%~44%。当滴灌灌溉量为3000m~3/hm~2、漫灌为5250m~3/hm~2时,苜蓿生产的综合经济效益最好。
英文摘要	It is of great significance to explore the effects of different irrigation methods and quantities on soil water spatial distribution and transfer in alfalfa field in Xinjiang oasis, two-factor experiments with two irrigation methods and three irrigation gradient treatments were conducted and soil water content was measured and analyzed during the alfalfa growth period in the second year. The results showed that with the advancement of growth process and irrigation frequency increase, soil water content exhibited a significant fluctuation decreasing trend during the alfalfa growth period. The soil water content in 0 to 40 cm in depth and in horizontal direction in 0 to 30 cm in depth were significantly increased, and the moist peak of soil water in the vertical direction was larger than that in the horizontal direction. With the increase of irrigation quantities and harvest times, water use efficiency gradually decreased during the alfalfa growth period. The water use efficiency under drip and flood irrigation were 4.55 to 5.48 and 3.21 to 3.81 kg/(mm·hm~2), respectively, and compared with flood irrigation, water use efficiency under drip irrigation method increased by 42% to 44%. The comprehensive economic benefit would be the best when the irrigation quantities were 3000m~3/hm~2 under drip irrigation and were 5250m~3/hm~2 under flood irrigation.
